Phase I

Contract Number: N68335-18-C-0329
Start Date: 4/25/2018    Completed: 10/26/2018
Phase I year
2018
Phase I Amount
$124,999
TrueNano, Inc. will in collaboration with the University of Colorado and industry partners, develop a novel single-wafer, high-throughput hot filament CDV reactor for the growth of high quality silicon carbide (SiC) epitaxial layers, suitable for the next generation of power electronic devices and systems. This includes the design and simulation of the reactor, the development of a throughput model, a growth model and cost model and the simulation of the reactor throughput and material uniformity. Filament reliability will be determined based on lifetime measurements and failure analysis. HFCVD material will be characterized extensively and used to demo a device with high breakdown field. This proposed technology will ultimately result in lower cost SiC materials, devices and systems, due to faster throughput, larger wafer size, and higher device yield, as desirable for a multitude of military and commercial applications.

Benefit:
Silicon carbide power electronics are rapidly replacing their silicon counter parts, especially in advanced mobile platforms, where high efficiency or low power dissipation is paramount, and where operation at higher switching frequencies contributes to the reduction of volume, weight and cost of the balance of materials. This in turn translates to reduced fuel consumption, increased range and reduced cost of advanced mobile platforms, while adding the increased ruggedness needed to operate in harsh environments. As the cost of SiC material and devices is reduced, this technology will become the preferred technology for high voltage systems, delivering better performance at lower cost.

Phase II year
2020
Phase II Amount
$374,366
TrueNano, Inc. will in collaboration with the University of Colorado and industry partners, produce a novel single wafer, high throughput, cold wall Hot Filament CVD (HF-CVD) reactor prototype for the growth of high-quality silicon carbide (SiC) epitaxial layers, suitable for the next generation of power electronic devices and systems. This includes the design and simulation of the reactor chamber, the modification of existing CVD reactor designs to include suitable filaments and to demonstrate high growth rate, high throughput, and low cost of ownership of our HFCVD technology. HFCVD material will be characterized extensively, providing wafer maps of epitaxial layer doping and thickness with non-destructive wafer-scale measurements as well as Schottky diode arrays that also provide breakdown field data. The HF-CV D technology is anticipated to result in lower cost SiC materials, devices and systems, due to faster throughput, larger wafer size, and higher device yield, as desirable for a multitude of military and commercial applications.
